HAY sTAcKER AND LOADER.

Specification of Letters Patent.

Patented Apr. 2, 1912.

Application l'ed November 29, 19.10. Serial No. 594,693.

To all 'whom itV may concern.'

Be it known that I, LE ROY R. SHAF'ro, a citizen of the United States, residing at Elm Creek, in the count-y of Buffalo and State of.

Nebraska, have invented a new and useful Hay Stacker and Loader; `and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will'enable others skilled in the art to which,

310 it appertains to make and use the same.

This Vinvention relates to an improved hay stacker and loader.

The principal object-of the invention is to provide a support having an inclined .15 track upon which a fork is adapted to be elevated and dumped.

A further object of the invention is to provide an improved recoilwarrangement which will assist in returning the fork to its normal lposition after dumping.

A still. further object of the invention is rto provide a structure .for the purpose described which is comparatively simple vin construction, easy lmof operation and cheap to manufacture.

invention consists in the construction and' novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out inthe claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within'the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :-Figure 1 is a perspective view of the stacker showing the fork in its lowermost position. Fig. 2 is a side elevation of the stacker, showing the track in-position employed previous to the beginning of the movement ofthe fork, the dotted lines showing the fork when in its uppermost or dumping position. Fig. 3 is a `detail plan view of the baseshowing only yone sirine 12. Fi 4 is a detail pers ective l a g P view of the roller supporting brackets of drawings.

the fork, and Fig. 5 y1s a perspective view of-one of the rope pulleys. Like reference numerals designate correspending `parts in all the figures of the l Referringy to the drawings, the invention comprises a base consisting of spaced longi- `by transverse bars 21.

tudinal. beams 5-5 connected at suitable intervals by -transverse members 6-6. The

vbeams 5 are furthermore connected centrally by means of a transverse support 7.

'Associated with the transverse members 6-6 are upwardly and inwardly extending braces 8, the upper ends thereof supporting a cross head 9, which is adaptedto receive a rotatable spindle 10 the upper end thereof projecting above t' e cross'head and the lower` end suitably journaled in the transverse 'membei 7 by any suitable means.

`Transverse eye-bolts 11- are secured to the beams 14. Connected between the eye-bolts 11 andthe eye-bolts 13 are springs 12, thus constituting means for tensioning the beams 14 as they are moved. In Fig. 3 of the drawings there is only one spring 12 illustrated, which is connected between the eye. '13 of the base, and the eye 11b of the spindle 10. The purpose of the spring 12 in Fig. 3 is the sameas'the springs 12 in theother figures of the drawings, that is, to resiliently hold'the spindle 1D in its normal position, as will be-readily observed. The two springs 12 Iin Figs. 1 and 2 are connected to the ends ofthe beam 14. Also secured to the spindle 10 :and preferably below the eye-bolt V11 is a horizontally arranged beam 14 secured in place by any suitable means. -A brace 15 has yits free ends rigidly connected to the ends of the'beam 14 and has its central portion connected to the spindle 10. Associated with each end of the beam 14 are eye-bolts 16, to either one of which may be detachably secured a block 17 for apurpose hereinafter described.

Fixedly secured to the upper end of `Jche spindle 10 is a cross bar 18 which is suitably braced by members' 19. Journaled. on the ends of the bar 18, is a fork supporting track frame which consists of longitudinal tracks 20-20, which are suitably connected This fork frame is pivoted at `one side at `its center to form a :short lower end and a long .upper end, `designated respectively bynumerals 22 and 23, the lower ends of veach trackmember 20,

being preferably undercut, as yshown by reference-numeral 23, and provided with stop blocks 24 arranged -on the A,underside of the track members 20. `The track members 20 are journaled upon 'the bar 18 in order to have vertical pivotal movements., The upper ends of the track members 20 are downwardly curved as shown by reference numerals 25, and are provided on their extreme ends with stops QG.

The invention further comprises -a fork consistingI ol a plurality of angularly disposed fork members QT and 28. These niembers are spaced a suitable distance apart and are connected by means oit transverse rods 2t), and Also carried by these rods Q) and BO, and spaced apart a suitable distance, are bracket members Bln-3l.

A. pair transverse rods 32 and have their respective ends bent downwardly at right angles, as shown by reference numerals 34 and 5, and have their free ends 36 and 3T respectively bent inwardly. The bent portions 3 and 85 ot' each member are secured te the brackets 31 by any suitable means, and associated. with the rods 32 and 3? and the inwardly extending end portions ite and $.37 are roller bearings 3S which ride above and below the track members' 20. rthese roller bearings are preferably flanged and each pair of roller bearinvs is disposed in angular relation; that is, the under bearinns are closer together than the upper ones.

tftmnected to the rod 30 of the fork, at opposite points, are cables 39 39. These cables have pulleys 40 which are journaled on the transverse connecting bar 2l of the track trame. They then pass downwardly around a pulley 4l carried by the spindle and thence under the block 17 hereinbefore mentioned. rthe free ends of the cable are connected to a swingle or double tree 42, 'from which point a. pull may be exerted upon the cable and thereby elevate the fork Aupon the .iframe in order to limit the inclination of the traine. A cable 43 has its ends connected to the lower ends of the frame by any suitable means 'and has its central portion connected .to the rope or cable 44, the free end ot which is detachably connected to the beam 14, a'lter having been passed through the eye bolt 44. By means elj this adjustment, it will be evident that the limit of inclination can be readily adjiisted.

rlhe invention further comprises another able 46, one end thereof being connected to .he transverse member It() of the trame, and the other end to the connection between the cable 4?) and the adjustment 44.

lt will he evident from the foregoing, that when pull is exerted upon the swingle tree 42, the track trame Qt), by means ol the cables Pit), will tend to elevate the l'ork frame. As the fork frame travels the track rails, the pull and weight of the material in the fork will tend to lower the upper end otl the frame. This downward movement ot the upper end of the frame is limited by means et the cable. 43 betore explained. As the fork reaches the upper end ot' the trame, the roller bearings of the fork will travel the curved ends 25 and will engage the stops QG. As the fork travels around the said curved ends, the material in the tork will, ot course, be automatically dumped. .lt will furthermore be noted at this point that at the time the fork is beim@T dumped, the cables 43 and 44 will be taut, thus preventing the fork from traveling ottl the curved ends of the tracks 20.

The rope or cable 44 has its end arranged in the recess a, and held therein by the pin co. This rope or cable may be arrzmged in any one ot the recesses a, t), c, (Z and o. However, any part of the rope or cable 44 may be pressed in these recesses and held therein by the pin 0f, thus shortening or lengtheningr the play ot the rope, and providing anchoring-means vtor the rope or cable 44. i

Having thus fully described my invention, what I claim new, and desire to secure by Letters Patent, is:-

l. In a haystacker, a base, track members` carried thereby, a fork n'iovable on the members, brackets carried by the fork, spaced rods connecting the' brackets, each rod having its end portions bent around the track members, rollers respectively journaled on each end portion ot' each rod above and below and engaging the track members, and means for elevating the fork alonfbr the track.

2. In a haystacker, a 'base having a partially revoluble spindle, track members movable thcrewith, a fork movable on the track members, the spindle having a transverst` beam, provided with a strap bracinj'g,l the beam with regard to the spindle, mians cooperating between the ends ot the beam and the base for resiliently holding' the spindle in position, and a cable connected between the fork and beam.
